Research And Development Of Limiter For Flxed And Gyrate Crane

Crane is a kind of large equipment for outdoors .,It easily has many kinds of dangers. Disresonable operation and overload can make crane turn over or break, and it will not go back to former state. So the crane over 16t shall be fited equipment named limiter for safe .On the basis of study of the limiter at home and abroad, this paper research an advanced limiter which takes advantage of progress of technology in the field such as electronic .computer, sensing and" testing. It not only provides these functions such as detecting, controlling, real time displaying and so on, but also can remind operator through the alarm of the light and voice. This paper mainly improves the advancement and credibility of crane.On the basic of over-all designing of the limiter, this paper develops the whole limiter system, designing entirely circuit and compiling the controlling program with compilation language. In addition, this paper adopts a series of hardware and software protecting measures to enhance the ability of antijamming.
